    The molecule contains three functional groups: an amine, and carboxylic acid and an amide.

    The amine would be protonated (an ammonium cation) at pH 7

    The carboxylic acid would be deprotonated (a carboxylate) at pH 7

    The amide is incorrectly drawn in the protonated state. Remember that amides are NOT basic, so this state is not reasonable. The amide group should be drawn as an uncharged group (with only one hydrogen)
